We present the first measurements of ion rotational distributions for photoionization over an extended range [0 ≤ E_K ≤ 200 eV for N_2 (2σ^(−1)_u ) and 3 ≤ E_K ≤ 125 eV for CO (4σ^(−1))]. The N_2 ion rotational distributions are seen to

We present the first measurements of rotational distributions for photoionization over extended energy ranges [0 ≤ E_k ≤ 200 eV for N_2 (2σ^(-1)_u) and of 3 ≤ E_k ≤ 125 eV for CO (4σ^(−1))]. The N_2 and CO results show a strikingly unusua

We report a vibrationally resolved investigation into the 5σu−1 shape‐resonant ionization dynamics for CS2 in the range 18≤hν≤30 eV. The intensity of dispersed fluorescence from CS2+(B 2Σu+) photoions is measured to obtain partial photoion

We present rotationally resolved data for the v’=0 and v’=1 levels of N2+(B 2Σu+) produced via 2σu−1 photoionization of N2. The data are obtained over a broad photon energy range (19≤hνexc≤35 eV). This is made possible by using synchrotr

We have measured vibrational branching ratios for 4σ −1 photoionization of CO in order to characterize continuum channel coupling. The results indicate that the shape resonance in the 5σ→ϵσ channel influences vibrational branching ratios of t
